ANVIL ATTACHMENT.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application led .Tune 18, 1912. Serial No. 704,313.

To all whom 'it may concern Be it known that I, JAMES R. STULL, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented a new and Improved Anvil Attachment, of which the following is a full, clear, and exact description.

My invention relates to anvils, and it has for its object to provide an attachment for an anvil having an arm, which extends through an opening in the top of the anvil, the arm being provided with a head, which projects longitudinally of the anvil at opposite sides of the arm, the arm being pivoted to a lever, fulcrumed to the anvil block, so that this lever may be operated by the 'foot of the smith, to conveniently clamp the member between the head and the anvil.

Another object of the invention is to provide means for conveniently securing the anvil to the anvil block.

Still other objects of the invention will appear in the following complete specification, in which the preferred form of the invention is disclosed.

1n the drawings Similar characters ot" reference indicate corresponding` parts in both the views, in which Figure 1 is a perspective view of an anvil provided with my attachment; and Fig. 2 is an enlarged end view of the said anvil provided with my attachment.

As my attachment is constructed it may be used for bending, offsetting and holding metal, the attachment acting asa vise to assist a smith in bending and twisting iron in almost any manner or shape, it being possible, with my attachment7 for a smith, without a helper, to bend at right angles a steel bar three inches by one inch (3X1) in one heat, which it is quite impossible to do unless the attachment disclosed in this appli cation is used to assist the smith.

By referring to the drawings it will be seen that on the anvil block 5 there is disposed the anvil 6, this anvil 6 having the usual flanges 7. Through the anvil block 5 there is an opening 8, through which is disposed a bar 9, this bar 9 projecting beyond the sides of the anvil` block 5, and being provided with two orifices at each terminal, these two orices 10 at each terminal being disposed substantially at right angles to each other. Through these orifices aredisposed the threaded terminals 11 of theU- shaped holding members 12, these U-shaped holding members 12 being disposed over the fianges 7, with their threaded terminals disposed through the orifices 10, so that when the threaded terminals are engaged by the nuts 12, and the said nuts are turned home, the nuts will press against the terminals ol the bar 9, and will hold the U-shaped members down and against the flanges 7 of the anvil 6, by which means the anvil 6 will be held securely in position on the anvil block 5.

Through the opening 13 in the flange 14 of the anvil 6 there is disposed an arm 15, the upper terminal of this arm 15 being provided with a head 16, which projects in opposite directions and longitudinally ot the top of the anvil 6, so that either proljection of the head 16 may engage the top of a piece of iron 17, which is being Worked to press the said piece of iron against the flange 14 of the anvil 6, and, in this way, hold it securely in place while the piece of iron 17 is being worked by the smith. The lower terminal 18 of the arm 15 is disposed through a slot 19 in a lever 20, and in this lower terminal 18 of the arm 15 there is an orifice, which is in alinement with the orifice 21 in the lever 20, the said orifice 21 extending to the slot 19. The arm 15 is articulated to the lever 20, by the pin 22, which is disposed through the orifice :21 in the lever 20, and the orifice in the lower terminal 18 of the arm 15. To prevent the pin 22 from working out ot' position, the

lever 21 is provided with a spring member 23, which presses on the head of the pin 22, and serves to hold the pin in position. In order that the pin 22 may not become lost when it has been moved from the orifice, it is connected with one of the U-shaped members 12 by means of a chain 211. The lever 2O is pivoted to the anvil block 5 by means of a pin 25.

When the anvil 6 has been firmly secured to the anvil block 5 in the manner described, the arm 15 is disposed through the opening 13 in the flange 111 of the anvil, and in the slot 19 of the lever 20, the lever 20 having been previously disposedwith its orifice 26 in registry with the pin 2550 that when the lever 2O is moved toward the anvil block 5 the pin 25 will enter the orifice 26 in the lever 20. After this has been done the pin 22 is disposed throughthe orifices in the lever20 and the lower terminal 18 of the arm 15, aifter which the spring 23 is released, to engage thepin 22 and hold the pin in place.

Itwill readily be understood .that when the lever 20 is moved upward bythe loot of the smith, the` head 16 will be raised, to permit 'of the insertion 'of a piece of iron 17, between one of the projections lof lthe said head 16 and the anvil 6. As the head :projects longitudinally of the top of the' anvil 6, it .is possible to secure the `piece l"of imon, which ,is being worked transversely .of the anvil, which permits the smithv to bend the ,piece of viron on ythe `anvil at either side of fthe head `16 Vin many diiierent ways. ln fact, with "this attachment .it is possible .for fthe-smith without a helper Atobend the piece of iron which is yto be. worked in practically :anymanner desired.

.@As a lockingzmeans for the lever .2O I provide a curved arm 27 with teeth 28, this arm 27 being Ipivot-ed to the lever 2O at. Q9, and having `a bent .terminal .30 which extends up and through an opening 2in the lever F20, Vso that :the terminal 30 .may be pressed :down 'by the foot 'after the lever has 'been moved down :to the desired I'position by the .foot of the smith. This ycurved arin '27 passes through a slot B2 in `strap', the outer lower fend of which .is Jheld 'in position .relatively to the anvil block v5 by a pin 341 which .meshes in threaded openings in .the strap 33 land in the anvil 6. It will therefore :be seen that when the terminal 530 is pressed down the. curved arm at `the teeth y@Savill be .moved up, and kthatthe said teeth will engage the strap at the top of the slot `to yhold 'the :lever 2O in place. To free the lever 2O or v.the piece of iron 17 when .the 'locking .means is in useallthat it is necessary "to 'dois tor the Vsmith to 'put pressure on the 'lever2`O,-and the weight of the :arm 2T causes l"thelarm vto drop and disengage it from the -strap 33, freeing 'thepiece or iron 17, as soon 'ras 'the lever E20 .1s raised.

Having thus ldescribed my invention l claim as new anddesne to secure by Letters Patent:

ti'cally to 'clamp a member to the anvil, a

lever pivoted adjacent the bottom or' the anvil,`means by which the head may be operated by the'lever, an arm pivoted to the leverwand curvedv around the Yi"ulcrum of the lever, the armhaving teeth for engaging the 'tirstanentioned member for holding the lever .against movement. n

B. An anvil having a strap for engagement by teeth, a head for clamping a member tothe anvil, a lever fulcrume'd relatively lto the anvil, vmeans by which the head may be operated by the lever, an arm pivoted to the lever and disposed in ithestfrap, thear'm having teeth for engaging the strap for Y ber, for holding the lever against movement,

the arm having `a surface adjacent the lever .for the lpurpose specified.

In an anvil, a vmember lfor fengagement 4 by yan larm, ahead forrclamping a member to the anvil, a lever having an opening, means by which the head is operated by the lever, an arm plvoted tothe lever, and having a :surface for engaging the ffirst-unentioned :member for holding the lever against movement, the arm having a terminal extending through the opening .in `the lever for the Y 'purpose speciiied.

6. In an anvil, a memberadapted to "be enga ged by an arm, a head for moving down to yclamp a member -to the anvil, a lever disposed below the 'first-mentioned member and kpivoted to the anvil, lmeans by which ythe Vhead may be operated by `the lever, and an' arm carried by Ithe Alever for engaging the irstmentioned member for holding -the lever against movement;

7. .ln combination with an' anvil having an opening through lits top, an arm disposed in the opening land having .a head which projects beyond'the arm, there being Jan orifice in 'the arm, a .lever fulcrumed relatively to the anvil Vand having an opening in which is disposed the arm at vthe oriiice, the lever havingoriices leading to the opening, a pin disposed in the orifices in the lever, andthe orifice in the arm, and a spring on the arm for engaging the pin for holding the pin in position.

In testimony whereof I have signedV my nase to this speciiication in the presenceof two subscribing witnesses.
